While the games in this table are developed under an open-source license, the reuse and modification of only the code is permitted. As some of the games' content (sound, graphics, video and other artwork) is proprietary or restricted in use, the whole games are non-free and restricted in reuse (depending on license). The motivation of a developer to keep the own content non-free while he opens the source code is most often the protection of a game as sellable commercial product. Sometimes the motivation is the prevention of a commercialization of free product in future, e.g. when distributed under a CC NC license.

Open-source remakes with non-free content from the proprietary original[edit]

The video game remakes in this table were developed under an open-source license which allows usually the reuse, modification and commercial redistribution of the code. The required game content (artwork, data etc.) is taken from a proprietary and non-opened commercial game, so that the whole game is non-free. See also the Game engine recreation page.

For video games in this table the source code is available but they are neither open-source software according to the OSI definition nor free software (see software with source available). These games are released under a license with limited rights for the user, for example only the rights to read and modify the game's source for personal or educational purposes but no reuse rights beside the game's original context are granted. Typical licenses are the creative commons "non-commercial" licenses (e.g. CC BY-NC-SA), MAME like licenses or several shared source licenses.

1998 freeware DOS platform video game, written in C and Assembly language by Brainchild Design. The source code was released in 1999, then source ported to several other operating systems and platforms via SDL.

The source code of the 2008's Windows freeware version was published under a software license permitting noncommercial distribution and modification on December 25, 2009.[62] Based on this source code the game community created a community patch which added support for Mac OS X.[63][64] For the later remade 2012 release the source code wasn't provided, only for the 2008 "Classic" Spelunky version.

^Simser, Bil (2008-01-10). "SimCity Source Code Released to the Wild! Let the ports begin...". weblogs.asp.net/bsimser. Retrieved 2012-12-30. [...]Don Hopkins got a lot of work done on the finishing touches on releasing the original SimCity source code under the GNU General Public Library (GPL). The code won't have reference to any SimCity name as that has all be renamed to Micropolis. Micropolis was the original working title of the game and since EA requires that the GPL open-source version not use the same name as SimCity (to protect their trademark) a little work had to be done to the code.
